If you are traveling in a car with the windows up and a fly is buzzing around inside of your car and you crash what happens to the fly.

Does nothing happen?

Or

Does it slam into the windsheild?


Oh yea also, if you are traveling at the speed of sound and fired a bullet, which travels at the speed of sound,

Does the bullet come out of the gun


Or

Does it travel at twice the speed of sound?
 
??? Ok I guess I will take this one.
If the laws of nature apply to this car then the fly is traveling at the same velocity as the car plus his flight speed. So, and object in motion stays in motion until stopped. In this case it would be subject to the same G forces and slam into what ever was in front of it.
That was to much thinking for a Friday. :p

The fly WILL slam into the windshield right befor my head hits the fly :0

The bullet well I have a .45 which is sub-sonic so it should(with my logic so far) go backwards hitting the shooter, which is why my head hits the fly going into the windshield :laugh:

Read the question. The bullet travels at the speed of sound too.

In this case the bullet which is already traveling at the speed of sound inside the gun in the hands of the shooter which is traveling at the speed of sound, when fired it would achieve its maximum velocity (speed of sound) and since it is already traveling the speed of sound it would achieve a velocity of 2x the speed of sound.

It is the same as saying that I can throw a ball 50mph. If I am in the back of a truck driving 50mph and throw the ball it does not just stick to my hand.

Now the real question is when you fire this hypothetical bullet while traveling the speed of sound . . . what do you hear? If anything?
 
1. The fly will continue forward until it hits an interior surface. If you go head-on into an abutment, the fly will continue forward until it is stopped by the windshield or some other surface. Newton's First Law.

2. The bullet will exit the gun. Relative to the gun barrel, it will be traveling at the speed of sound. Relative to a stationary object, it will be traveling at twice the speed of sound.

At these speeds, no correction for special relativity are required.

Now let me ask you one. If you are in a spaceship and you are traveling at the speed of light and you turn on a flashlight that is pointed ahead of you, what speed will that beam of light be traveling relative to you? A bystander? What if you point the flashlight to the rear?

In my opinion the fly does not have to hit anything. I don't think it has enough mass to be propelled in the glass especially if it was flying away from it and you crash in the car in front of you.

To answer this one correctly you need to know the mass of the fly the direction in which it was flying and the speed at which it was going in that direction as well as the side of the impact and its direction to the flies path

My dad was a Physics proffesor at college so growing up I loved the Law of Relativity :whistling:
 
Or here is a relevant question:

What is the last thing that goes through the fly's mind as it hits the windshield?

I don't care who you are that's funny.
 
Too many factors can contribute to what happends in the fly question; size of the car, reflexes of the fly, cars speed, cars deceleration, etc. The bullet however will leave the gun as the initial velocity is the speed of sound, and the average speed of a bullet is about 1000 fps or 304 m/s; the speed of sound being 340 m/s. So, the bullet will be traveling 644 m/s as soon as it leaves the muzzle of the gun. And, theoretically, if the car were to continue at the speed of sound, the bullet would decelerate enough to make it back into the barrel of the gun, provided there was no gravity and only air resistance. I do love physics :)
